This invention relates to a web or tally strip supporting and feedinginccliianism adapted for use with typewriting machines. 'An object ofthe invention to provide improved means for feeding a tally strip orother webfrom a supply roll over the machine platen and onto a storageor Windmg roll, the web-feeding mechanism being "Pemted by e linespacingmechanism f the machine for feeding the telly strip a single linespacedistance each operation of the line-spacing mechanism whether the latteris set for single, dounle, or Wider line spacing. Provision is also madefor maintaining the line spacings of the web uniform regardless of theincreasing iameter of the winding roll.

The invention further provides means for automatically advancing thetelly strip aline-space distance each time a work-sheet is removed from.the machine and replaced by a new sheet, so, that a blank portion of thetally strip will be presented to receive lever. The tally strip is therecord of the first line written on the new work-sheet without requir ngthe oper-- ator to operate the line spacmg mechanism a fter the lastline of a sheet has been written.

The tally strip mechanism may be mount ed on the typewriter platenframe, and coinprises a support for a supply roll from which .the tallystrip extends around the platen and to a pair of feed rolls, one ofwhich is mounted o'ri'a drive shaft extending parallel with the platenand connected through suitable gearing to be rotated by the line-spacedrawn forward over the platen by said rolls, and after passing betweenthe rolls is woundon a winding spindle orl mandrel to form a recordroll.

The winding spindle is driven by the said drive shaft through gearingcomprising a slip connection, permitting the speed of the winding sindle to accommodate itself to.

the gra-dua ly increasing size of the storage roll. The winding spindlemay at any t1 me be withdrawn in a longitudinal direction moved from therecord roll, leavingthe latter free to besevered, by means of a. tearingblade, from the remainder of the web, and removed from 'tliemachine.Tension springs bearing on the supply roll serve not only to prcventslack in the tally strip, but also to prevent the tally strip from beingfed forward by the platen more rapidly than it is fed, by the rallystrip feed rolls. The usual key for thmwing the main feed rolls oil theplaten is connected through a pawl-andratchct mechanism, to operate thedrive shaft for the telly strip rolls, and advance the tally stripwhenever the key is operated to perm t a completed woik-sheet to he *dreplaced by a new one.

Other features inafter appear.

The typewriterplaten l is mounted on an axle 2 journaled in theplatenframe, comprising ends 3 and 4 connected byan inclined paper table5 at the intake side of the platen. Types 6, operated by the usualmechanism, strike againstthe work-sheet at loo the front face of theplaten. The platen may be rotated by hand wheels 7 or by the usualline-space mechanism comprising a line space'ratchet Wheel S'fixed tothe platen axle and driven by a pawl 9 pivoted at 10 to the plunger ordriver 11, actuated by the line-space lever 12.. The driver and pawl arereturned by a spring 13 connected at. its

and advantages will here and 17 which l "end brackets 26 and 27,

ends to the driver and platen frame respectively. The pawl 9 is held offthe ratchet wheel during the initial movement of the driver 11 by meansof a ledge 14 carried by an adjusting lever 15, which may be set topermit the pawl 9 to engage the ratchet wheel earlier or later in thethrow of the plunger 11 and thereby cause the ratchet wheel to berotated one, two, or more line-spaces, at each operation of thelinespace lever. Front and rear feed rolls 1G r against the under faceof the platen for feeding the work-sheets forwardly, may be thrown offthe platen by means of a key 18, on a lever 18, connected through a link19 to a rock shaft 20, having cams or flats 21 to engage lugs 22 onlevers 23, fulcrumed on a rod 24, said 1evers Supporting shafts 25 onwhich the feed rolls 16 and 17 are mounted. By depressing the key 18,the feed rolls are thrown off the platen, as indicated in Fig. 5. The

parts thus far described are those common to the commercial Underwoodtypewritmg machine.

i The tally strip mechanism is removably mounted on the platen frame bymeans of mounted respectively on the frame ends 3 and 4:. The tallystrip supply roll 28 is mounted on a rod 29 extending parallel with theplaten, and is removably mounted on the brackets 26 and 27, the latterprovided with openings 30 to receive and form bearings for the ends ofsaid rod. The rod has portions cut away to provide necks 31 to enter therestricted portions 32 of the openings '30, and the rod is held againstaccidental displacement by a spring 33 which, as shown in Fig. 5, bearsagainst the fiat face of a neck 31, and holds the rod 29 against rotarymovement into a position to pass through the restricted portions 32 ofthe openings. The rod, however, may be readily removed by first rotatingit through a quarter turn by means of the km ed thumb pice 34. Thesupply roll 28 is held against longitudinal displacement by means of apair of leaf springs 35 which further serve as tensioning means for thetally strip, as will more fully appear hereinaftcr.

The tally strip extends from the supply roll 28 downwardly around theplaten and up to and between a pair of feed rolls 3t) and 37, which forma feeding couple to draw the web forward over the platen. From thefeeding couple the strip extends rearwardly to a winding spindle 38 onwhich it is wound to form a record roll 39. The rear feed roll 37 ismounted on a drive shaft 40, which is journaled near its ends in thebrackets 26 and 27. Intermeshing gears 41 and 42, connected respectivelyto the rolls 36 and 37, cause both said rolls to be positively driven atthe same peripheral speed when the drive shaft is rotated. These feedrolls are provided with a facing of rubber or other suitablecompressible friction material. The drive shaft 40 may be rotated tofeed the tally strip forwardly, by means of a gear train connecting saidshaft to the line-space mechanism. Said train comprises'a pinion 43 onthe shaft 40, and running in' mesh with a pinion 41 on a stud shaft 45mounted in the bracket 26. Connected to rotate with the pinion 14 is aratchet wheel 46'driven by a pawl 47 pivoted to a rock arm 18 journaledon the shaft 45. Said rock arm 48 is connected through a link 4!) to thedriver 11, so that each time the line-space lever 12 is operated, theratchet wheel lb is rotated the angular distance between two adjacentteeth thereon. said rotation being imparted to the tally strip feedrolls through the gearing just described. and the tally strip thus fedforwardly a line-space distance It will be noted that the extent ofrotation of the ratchet wheel 46 is the same for each line spaceoperation, regardless of whether the lever 15 is set for sin le, doubleor wider line-spacing. The ta ly strip may pass around the platen at aposition between the main feed rolls 115 and 17, so that the pres sureof said rolls will not be applied on the tally strip. The platen has atendency to feed the tally strip forwardly faster than it is fed by thefeeding couple '36, 37, particularly when the line-spacing mechanism isset for double or triple line-spacing. The tension springs 35, however,exert a braking aetion on the supply roll 28 suflicient to take thetally strip out of the control of the platen. In other words. the pullof the platen on the tally strip is insullicient to rotate the roll 28against the holding power of the springs 35, so thatthe. web is only fedforward at the peripheral speed of the rolls 36. 37. After passingbetween the feed rolls 36 and 37. the tally strip is wound onto the.receiving spindle or mandrel 38 driven from the shaft 4) through a trainof gears 50, 51. The gear 5] may be. connected to the drive shaft 40through the intermediary of a sleeve loose on the shaft and providedwith an extension 53 forming a pair of clamping jaws surrounding theshaft and said jaws may he caused to grip said shaft by means of a setserew 51, thereby connectiug the gear 51 to rotatewith said shaft. Thefeed rolls 3 and 257 and the spindle 38 are mounted in a framecomprising end plates or brackets 55 rigidly connected as by means of abar (32 which serves as a tearing blade. and a rod 62" (Fig. ill. Saidframe is slidably mounted on the drive shaft 40 and the rod 29. so thatby loosening the set screw 54, the frame may be adjusted to bring thetally strip and its supporting rolls to any position along the platen,and then secured in adjusted position by setting up 3 the screw 5%. Themandrel 38 is preferably tubular, and is split by means of oppositelydisposed slots 56 extending longitudinally thereof, said slots providingmeans for securing the end of the tally strip to the man? drel, and alsopermitting themandrel to be withdrawn longitudinally from the recordroll as indicated in Fig. Byrefercnce to Fig. 7. bracket is formed witha tubular extension 57, in which the mandrel 38 is both slidably androtatably supported. Said extension also forms a bearing for ahub 58 onthe gear wheel 50.

A. slip connection between the gear and the mandrel 38 is provided bymeans of hollow bearing blocks 59 containing leather or other suitablefriction material, said blocks mounted in openings in the hub 58 andplaced under a yielding radial pressure causing the frictional materialto bear on the mandrel 38. The pressure is produced by a U-shapcd leafspring 60 (Fig. *1),

- cured by a screw (31 to the hub 58, and having its ends bearing ontheblocks 59. The

mandrel 38 is of sufiicient size to always wind the tally strip as fastitist'ed forward by the feed rolls 3G, 37, and the slip connectionjustdescribed, permits the speed of the mandrel to be reduced tocompensate for the increasing size of the record roll..

in other words, the peripheral. speed of the record roll on the mandrelis always the same as that of the feed rolls 36, 37.

To connect the end of the tally strip to the mandrel 38, the latter maybe turned to bring the slots 56 in alinement with the forwardend of thetally strip as the latter is advanced from the feed rolls 36, 37. Saidend is then introduced into the slot 56 and the mandrel rotated a shortdistance by,

hand. When it is desired to remove the record roll that has been woundon the mandrel, the latter is withdraw-'11 longitudinally tothe'position shown in Fig. 3 thus entirely disconnecting it from theroll which may the .movement of the mandrelto the right, by beingbrought up against the hub 58,-in which position, the right-hand end ofthe mandrelhas a bearing in the right-hand bracket The gear 50 is heldagainst endwise displacement by the left-handbracket' 55 hearing againstone end of the hub 58. and by a. disk 66 which lies against thelettdiandit will be seen that the left-hand face of the gear Wheel 51, said diskextend ing to the outer periphery formed by the teeth of the gear 51-,so that it always overlaps the teeth of the gear 50. The disk 60' may beformed integral with the sleeve 52 and form a connecting means betweensaid sleeve and-the gearfil.

The tally strip feed rolls 36. and 37 may be separated to permit thetally strip to be readily inserted or removed by the followingarrangement: The roll 36 is loosely mounted on a shaft 67 havingeccentric or offset ends journaled in the brackets 55. To the righthandend'of the shaft (37. is secured a-hand lever 68, which may be thrownforwardly to the Fig. 6 position, thus rotating the shaft 67 on itseccentric bearings. and separating the roll 36 from the roll 37. 'Theeccentric movement of the shaft 67 is insufiicient to; disconnect thegears 41. &2, which preferably remain permanently in mesh. When thelever 68 is thrown rearwardly, the roll 36 is thrown into engagementwith the roll 37. A spring 69 serves to hold the lever 68 in eitherposition and when the rolls are together. provides suitable pressurebetween the contact surfaces of the rolls.

In practice. the tally strip is generally used to receive the carbonrecord of items printed on the original bills or work-sheets, which areplaced on the platen in position to overlap the tally strip, a carbonstrip 70 being interposed between the original and the tally strip.Thecarbon-TO is usuallya continuous strip fed with a the tally stripfrom the supply roll 28. but it need not-he passed between the feedrolls 36, 3'? as it is carried along by the tally strip and overlyingWork-sheet. The reason for providing these overlapping portions upon theoriginal bills is to enable the rolls to press the bills against theplaten to travel therewith, at a greater speed than thatot the tally.strip which intervenes between the original bill and the platen. Therolls referred to must not therefore press the outer sheet against theslowly moving tally strip. The control of a Wide sheet by means of rollsengaging its overlapping portions is disclosed in'the patents to Kunath817,924, and McCormack 975,264. a

V. In order to place the supply roll 28 in position, therod 29 isremoved and the roll 28 comprising the tally strip and carbon' strip,slipped endwise thereon and then replaced (see Fig. 8) with the rollbetween the tension springs 35. The free ends of the strips arethencarried downwardly around the platen, and the end of the tally stripdrawn upwardly and fed between the separated feed rolls 36. 37, andconnected to the mandrel 38 as before described. The lever 68 is thenthrown backwardly, to grip the tally strip between the feed rolls, sothat the tally strip and its carbon may be'fed for- .mechanlsm to feedward as the line-space lever is operated to feed forward the originalwork-sheet which is placed on the machine when the tally strip is inposition. When the entries on the worksheet have been completed, the key18 is depressed to throw the main feed rolls off and permit the sheet tobe removed and a new one substituted.

In order that the tally strip may be advanced when the last line on anoriginal sheet has been written, and before the succeeding sheet hasbeen written upon, mechanism is provided for operating the feed rolls36, 37, by the key 18. Such mechanism comprises a ratchet wheel 71 fixedto the righthand end of the drive shaft 40 and operated by a pawl 7 2pivoted on a rock arm 7 3 journaled on the drive shaft 40, said rock armconnected through a link 74 to an arm 7 5 of the key lever 18, so thatwhenever the key 18 is depressed, the pawl 72 is operated to rotate thedrive shaft and feed the tally strip forward.

Although the invention has been particularly described as adapted foruse in connection with a tally strip, it will be understood that it mayalso be adapted for use with continuous strips or webs designed forother purposes.
